Retractable venting tool

Abstract

A Retractable Venting Tool has a needle with a point and an opposite shank, a knob connecting to the needle proximate the shank, a barrel receiving the needle and a primary slot guiding passage of the knob, a front spring near the tip, a rear spring away from the primary slot, and a clip outside of the barrel. The barrel has ridges outward of the primary slot, a shoulder outward of the ridges, and a head opposite the tip. The front spring compresses upon advancing the knob and needle outwardly from the tip. Upon completion of venting of a fish and turning the knob, the front spring retracts the needle abruptly. The rear spring compresses upon the knob being furthest from the tip. Before venting a fish, the rear spring imparts an axial force to the needle and cooperating with the knob retains the needle inside the barrel until needed.
